A.T. Robertson Commentary Romans 7:23

"but I see a different law in my members, warring against the law of my mind, and bringing me into captivity under the law of sin which is in my members." — Romans 7:23 (ASV)

A different law (ετερον νομον). For the distinction between ετερος and αλλος, see Ga 1:6f.

Warring against (αντιστρατευομενον). Rare verb (Xenophon) to carry on a campaign against. Only here in N.T.

The law of my mind (τω νομω του νοος). The reflective intelligence Paul means by νοος, "the inward man" of verse 22. It is this higher self that agrees that the law of God is good (12,16,22).

Bringing me into captivity (αιχμαλωτιζοντα). See on this late and vivid verb for capture and slavery Lu 21:24; 2 Corinthians 10:5. Surely it is a tragic picture drawn by Paul with this outcome, "sold under sin" (14), "captivity to the law of sin" (23). The ancient writers (Plato, Ovid, Seneca, Epictetus) describe the same dual struggle in man between his conscience and his deeds.
